1. See SIZE RANGE OF STANDARD RINGS chart here for other widths which are available. Radial load and torque capacities are generally proportional to width. Performance is influenced by design of mating components and assembly procedures - actual capacities may vary from the stated values. For sizes or load requirements other than shown, contact our Engineering Department for recommendations.

2. Diametral clearance or Diametral Gap is the void where the Tolerance Ring fits (mathematically represented by D-d) The size of this gap determines the amount of interference fit. G1 and G2 are design limits.

3. Torque capacity is dependent on fit. Torque Capacity @ G1 is the expected torque capacity at the tightest fit allowable. TC is the expected minimum torque transfer capacity at the Typical O.D. For Torque diameter range (which occurs with d min).
